Title: Improvements in or relating to a moulding plant
IPC: B29C33/36
Filed: 1970-02-03
Abstract: 1,249,797. Moulding plant. R. ZIPPEL, [trading as RICHARD ZIPPEL & CO. K.G.]. 3 Feb., 1970 [22 Feb., 1969], No. 5091/70. Heading B5A. In a plant for moulding articles from plastics material, particularly foaming material, moulds 2 and associated self-locking closure means are indexed on plates 1 through a filling station 4, an infra-red heating oven 6, and an article removal station 8, means being located between the filling station and the oven and the oven and the removal station for closing the mould and opening the mould respectively. Each closure means includes a lever and an actuating member 3 whereby opening and closing may be effected. In one embodiment (see Fig. 1a), control cams 5A and 7A which engage the actuating members are located in the appropriate parts of the mould path. In another arrangement, the cams are replaced by reciprocable pistons (see Fig. 1b, not shown) and in a further arrangement the cams are replaced by a single centrally located two-way piston (see Fig. 1c, not shown). In the embodiment shown in Fig. 2a the mould closure means comprises a lever 9 centrally pivoted at 10 and rigidly attached to the closure 2A at one end and pivoted at the other to a link 12. The other end of link 12 is pivoted at 13 to an actuating member consisting of a pin 15 slidably mounted in guides 14 and actuated to the left to close and lock the mould (as shown in the Figure) and to the right to open the mould by piston devices appropriately located along the mould path. In a second embodiment (see Figs. 3 and 3b, not shown) the closure means is basically the same except that the closure 2A is vertically slidably mounted upon rods extending from the mould and is attached to the lever 9 by a pin slidable in a slot in the upper end of the lever. In a third embodiment (see Fig. 4b) the closure 2A is pivoted at 26 to the mould and at 28 to a link 29 pivoted at its lower end in the slot of a lever 30 in turn pivoted at 32 to the mould. An extension 30b of the lever 30 is effectively the actuating member and is actuated to open and close the mould (see Fig. 4a, not shown) either by a piston or by a cam track as described above. In this embodiment, the closure means can be made to accommodate for various mould sizes by moving the pin 26 vertically or horizontally and shortening or lengthening, as the case may be one arm of the closure 2A. In a fourth embodiment (see Fig. 5b) the mould is carried by a support member 35 pivoted at 26b to an upper support member 35A, the closure 2A being carried from the upper support member by a link 39 and a lever 37, the upper end of which forms the actuating member. The mould is locked by a member 40 moved to the locking portion by a spring 42. In operation, upon actuation of the upper end of lever 37 the link is pivoted to the position shown, the closure being raised, and the member 40 being unlocked by a pin 44. Subsequently the closure 2A and upper supporting member are swung away to give access to the mould.

Title: Encapsulation of liquids in metal shells
IPC: B01J13/02
Filed: 1972-02-03
Abstract: 1351541 Encapsulating with metals BATTELLE DEVELOPMENT CORP 3 Feb 1972 [19 Feb 1971 7 Oct 1971] 5165/62 Heading B8C [Also in Division C7] A core-liquid is encapsulated within a metal coating by dispersing the liquid as droplets in a carrier liquid containing, or to which are added, a metallizing preparation (comprising a compound of a metal and an agent which will produce a metal therefrom by reduction) and a metal-organic surfactant (e.g. stannous octoate) which is at least partly soluble in both the coreliquid and the carrier liquid and the metal of which is more readily oxidizable than the metal of the metallizing compound. The surfactant "nucleates" the particles and allows the metal formed by reduction to deposit on, and form an encapsulating layer around, the liquid droplets. The procedure may be repeated to produce a thicker shell or additional metal layers (the same or different) may be produced by other methods, e.g. electrodeposition. Suitable metals for the coating are Ag, Au, Pt and Pd (all preferred), Cu, Ni and Co. The encapsulated liquid may be an oil (e.g. a silicone or mineral oil) when the carrier liquid is aqueous, or an aqueous or polar organic liquid when the carrier liquid is non-polar. Particular reference is made to the preparation of capsules having an electroconducting filling which may consist of a non- conducting liquid, e.g. silicone oil, containing carbon particles dispersed therein with the aid of a surfactant.
